[0002] Engines are widely used in vehicles such as automobiles and ships. The cylinders of existing engines generally adopt an L-shaped or V-shaped arrangement. They are connected by the piston pin, so the connecting rod and the piston will rotate relative to each other. When disassembling the cylinder liner, connecting rod and piston, due to the small internal space of the frame, the outside of the big end of the connecting rod is very easy to Collision with the inner wall of the frame and the cooling oil pipe in the cylinder liner, causing damage to the inner wall of the frame and the cooling oil pipe

Embodiment Construction
[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0044] The invention provides a dismantling tool, which is used to disassemble the cylinder liner, piston and connecting rod in the frame of the engine. The piston is installed in the cylinder liner, and the small end of the connecting rod is hinged to the piston. By adjusting the position of the piston in the cylinder liner, , so that the big end of the connecting rod protrudes from the cylinder sleeve, wherein the big end of the connecting rod is the end with an oblique cut. In this embodiment, the removal tool ...

The invention belongs to the technical field of engines, and discloses a disassembling tool used for disassembling a cylinder sleeve, a piston set and a connecting rod in a rack of an engine. The disassembling tool comprises a first disassembling assembly and a second disassembling assembly, the first disassembling assembly comprises a connecting part and an abutting part, the connecting part canbe detachably connected with the large end of the connecting rod, the abutting part is connected with the connecting part and can abut against the cylinder sleeve, and after the connecting part is connected with the large end of the connecting rod, the abutting part can abut against the cylinder sleeve to fix the large end of the connecting rod, so that the connecting rod cannot rotate relative toa piston, and damage of the connecting rod to the inner wall of the rack and a cooling oil pipe in the dismounting process is avoided; and the second second disassembling assembly is detachably connected with the piston so as to hoist the cylinder sleeve, the piston and the connecting rod. According to the disassembling tool, the disassembling operation of the cylinder sleeve, the connecting rodand the piston can be completed, meanwhile, in the disassembling process, the large end of the connecting rod can be prevented from colliding with the inner wall of the rack, and the disassembling efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a disassembly tool. Background technique [0002] Engines are widely used in vehicles such as automobiles and ships. The cylinders of existing engines generally adopt an L-shaped or V-shaped arrangement. They are connected by the piston pin, so the connecting rod and the piston will rotate relative to each other. When disassembling the cylinder liner, connecting rod and piston, due to the small internal space of the frame, the outside of the big end of the connecting rod is very easy to It collides with the inner wall of the frame and the cooling oil pipe in the cylinder liner, causing damage to the inner wall of the frame and the cooling oil pipe. [0003] Therefore, it is urgent to design a dismounting tool to avoid collision between the big end of the connecting rod and the inner wall of the frame and the cooling oil pipe when disassembling the cylinder liner, connecting rod ...
